Sufficiently more evolved is the second layer of Damasio's theory, Core Consciousness. This emergent process occurs when an organism becomes consciously aware of feelings associated with changes occurring to its internal bodily state; it is able to recognize that its thoughts are its own, and that they are formulated in its own perspective.

For example, primary consciousness includes a person's experience of the blueness of the ocean, a bird's song, and the feeling of pain. Thus, primary consciousness refers to being mentally aware of things in the world in the present without any sense of past and future; it is composed of mental images bound to a time around the measurable present.
Neuroscientists use empirical approaches to discover neural correlates of subjective phenomena; that is, neural changes which necessarily and regularly correlate with a specific experience. [3] [4] The set should be minimal because, under the materialist assumption that the brain is sufficient to give rise to any given conscious experience, the ...
The notion that quantum physics must be the underlying mechanism for consciousness first emerged in the 1990s, when Nobel Prize-winning physicist Roger Penrose, Ph.D., and anesthesiologist Stuart ...
While neural processes in the brain involve electrochemical interactions among neurons, the subjective experience of consciousness arises from these processes in a way that is not directly reducible to them. This emergence of conscious experience from neural substrates is a central topic in the philosophy of mind and cognitive science. [16]
Chalmers argues that facts about the neural mechanisms of pain, and pain behaviours, do not lead to facts about conscious experience. Facts about conscious experience are, instead, further facts, not derivable from facts about the brain. [27] [32] The hard problem is often illustrated by appealing to the logical possibility of inverted visible ...
The declaration says there is “strong scientific support” that birds and mammals have conscious experience, and a “realistic possibility” of consciousness for all vertebrates — including ...
The NCC are defined to constitute the minimal set of neuronal events and mechanisms sufficient for a specific conscious percept, and consequently sufficient for consciousness. In this formalism, consciousness is viewed as a state-dependent property of some undefined complex, adaptive, and highly interconnected biological system. [3] [4] [5]
